How it works

Voice Print Extraction — ECAPA-TDNN neural network converts a 10-second voice sample into a 192-dimensional mathematical fingerprint (the voice print)
Speaker Matching — Cosine similarity compares the voice print against the noisy recording to confirm the target speaker is present
Target Speaker Extraction — SoloSpeech cascaded generative pipeline isolates only the target speaker's voice from the mixture, removing all other voices and noise
Product Vision — Save voice prints to your Acoustic Contact Book. In a noisy restaurant, tap a profile → phone extracts that voice in real-time → streams clean audio to your hearing aids via Bluetooth

The hearing aid market is worth $9B+. 466 million people worldwide have disabling hearing loss. Current devices cannot isolate a specific voice in a crowded room.
